Abstract

An overview is given of mechanical, electrical and hybrid propulsion arrangements. The relation between propulsion concepts and power generation is explained and elaborated in energy flow diagrams. A general procedure for analyzing propulsion and power generation concepts is presented, using energy conversion effectiveness and based upon a selection of operational modes and a mission profile reflecting the use of those modes. Potential matching problems when switching between propulsion modes are identified and possible solutions given.
